Basics of As-Constructed Drawings

Written by: Angelica Bilangel

At Marblaze, electrical as-constructed drawings are one of the services that we provide. In general, as-constructed draws make up an important part of every building project. But, what makes them so vital to the process?

What are as-constructed drawings?

Simply put, as-constructed drawings are drawings created during the building of a construction project. They contain changes made to and deviations from the original plan during construction.

Who is responsible?

Although it is the architects and designers that create the original plans for a construction project, it is usually the contractors that are responsible for the creation of as-constructed drawings.

Contractors, on the other hand, are the people in control of the actual as-constructed drawings. When the contractors make decisions that deviate from original drawing in the construction, the drawings of their changes - the as-constructed drawings - are now owned by them.

Why are they important?

What makes as-constructed drawings so important is how greatly they are used as tools of reference. A good example is how they can be used as a base to help visualise future changes and revisions to a project.

Additionally, if issues in the construction were to occur, or if a specific item or object needs to be located, the as-constructed drawings make it easier for contractors to identify where they are, because of the specifications that they contain.

Conclusion

Without the use of as-constructed drawings, the organisation and execution of construction projects would be very difficult. They are drawings that contain changes and revisions made to a building during construction. As-constructed drawings become a good source of references as a base for planning, a tool for locating specifications, and more.
